Mask

Abstract

A mask for sealant curing includes an opaque region, a transparent region, and a partially transparent region. The transparent region is associated with a sealant region, which is to be cured, and the partially transparent region is disposed between the opaque region and the transparent region. RaysThe partially transparent region includes a pattern that has a regular shape or an irregular shape.

What is claimed is: 
     
         1 . A mask for curing sealant, comprising: an opaque region; a transparent region; and a partially transparent region, wherein the transparent region is associated with a sealant region which is to be cured, and wherein the partially transparent region is disposed between the opaque region and the transparent region. 
     
     
         2 . The mask according to  claim 1 , wherein the partially transparent region comprises a pattern having a regular shape or an irregular shape. 
     
     
         3 . The mask according to  claim 2 , wherein the pattern comprises:
 a plurality of opaque sections, a plurality of transparent sections and a plurality of partially transparent sections; or   a plurality of transparent sections and a plurality of opaque sections; or   a plurality of transparent sections and a plurality of partially transparent sections; or   a plurality of opaque sections and a plurality of partially transparent sections.   
     
     
         4 . The mask according to  claim 3 , wherein the plurality of opaque sections has a density in a vicinity of the opaque region that is greater than a density in a direction away from the opaque region. 
     
     
         5 . The mask according to  claim 3 , wherein the plurality of partially transparent sections has a density in a vicinity of the opaque region that is greater than a density in a direction away from the opaque region. 
     
     
         6 . The mask according to  claim 3 , wherein the plurality of partially transparent sections is a half-tone mask. 
     
     
         7 . The mask according to  claim 2 , wherein the pattern has a grid, serrate, triangular, or trapezoid shape. 
     
     
         8 . The mask according to  claim 1 , wherein the partially transparent region is disposed around the opaque region and in the form of a closed ring. 
     
     
         9 . The mask according to  claim 1 , wherein the partially transparent region is disposed at either side of the opaque region. 
     
     
         10 . A sealant curing method for a panel of Liquid Crystal Display (LCD), the method comprising:
 irradiating a substrate of a display panel by an ultra-violet (UV) light source using a mask,   wherein the mask comprises an opaque region, a transparent region and a partially transparent region,   wherein the transparent region is associated with a sealant region which is to be cured, and   wherein the partially transparent region is disposed between the opaque region and the transparent region.   
     
     
         11 . The sealant curing method according to  claim 10 , wherein the partially transparent region comprises a pattern having a regular shape or an irregular shape. 
     
     
         12 . The sealant curing method according to  claim 11 , wherein the pattern comprises:
 a plurality of opaque sections, a plurality of transparent sections and a plurality of partially transparent sections; or   a plurality of transparent sections and a plurality of opaque sections; or   a plurality of transparent sections and a plurality of partially transparent sections; or   a plurality of opaque sections and a plurality of partially transparent sections.   
     
     
         13 . The sealant curing method according to  claim 12 , wherein the plurality of opaque sections has a density in a vicinity of the opaque region that is greater than a density in a direction away from the opaque region. 
     
     
         14 . The sealant curing method according to  claim 12 , wherein the plurality of partially transparent sections has a density in a vicinity of the opaque region that is greater than a density in a direction away from the opaque region. 
     
     
         15 . The sealant curing method according to  claim 12 , wherein the plurality of partially transparent sections is a half-tone mask. 
     
     
         16 . The sealant curing method according to  claim 11 , wherein the pattern has a grid, serrate, triangular or trapezoid shape. 
     
     
         17 . The sealant curing method according to  claim 10 , wherein the partially transparent region is disposed around the opaque region and in the form of a closed ring. 
     
     
         18 . The sealant curing method according to  claim 10 , wherein the partially transparent region is disposed at either side of the opaque region.
